I really don't know if these fit any AK based rifle or not. Best idea is to check in at one of the gun forums that feature AK threads and ask this question there. No doubt someone has ordered one of these all the way from China and has all sorts of first hand experience to pass on.

the add said that the knife is said to fit on an ak, so i wouldn'tcount on it! there are many different kinds of ak's and there is no standard bayonet for them, some may fit different ak's but not all, take my word on it. cool knife but it would be the luck of the draw that it will fit your rifle.
